If you're not charismatic – you don't try to defend yourself – they'll run through their investigation and find something or find nothing, and then give a fairly fair verdict (or as fair as anything on Twitter ever is).
In this case, the author could've engaged, probably, and said something like:
> This was actually meant to be sarcastic; you're meant to notice how unreasonable it is, and disagree with the narrator, but the narrator doesn't represent my views, which are [XYZ]. Your advice would be good, if I actually agreed with what I'd written, but the point is that it's outlandish and bad, because I'm calling out attitudes in the game industry.
> The feature I'm documenting there is usually used for bad. Your suggestions would be good ones, if I actually believed in that bad, but I don't. Do you have any ideas for how to make it more obviously sarcastic?
I think the author probably missed the boat on this, though; the Twitter mob grows quickly.
The person who tried to warp this in to a social issue because they didn't like that they were being called out for using IAPs (being an abuser themselves really), is evil. This person is a harm to society.
If they had the intention you think they had? Evil. But I didn't get that from reading the archive.is link upthread.
